Hello, @paweł-łabno and All,

Not totally sure that is the right solution for you ! But let’s give it a try ;-)). I simply suppose that all your titles lay in a single line. So :

Open one of your html files, in N++
Fold all the sections with the View > Fold All menu option or use the Alt + 0 shortcut ( NOT from the numeric keypad ! )

=> The text collapses and you should see the <html> tag, only !

Then, open the Find dialog Search > Find… menu option or use the Ctrl + F shortcut
Type in the regex (?-is)(?<=<h1>).*?(?=</h1>) , in the Find what: zone
Select the Regular expression search mode
Click on the Find All in Current Document button

=> At once, the Find result windows pops up, at bottom of the screen, with all the <h1>....</h1> titles !

Now, simply double-click, in the Find result window, on one of these results. Immediately :
- Your HTML file should expand the zone, containing the corresponding <h1>....</h1> title ;-))
- All the title, between the boundaries <h1> and </h1>, is selected

Best Regards
